SPINNING FRAME SADDLE Appli'cati'on filed July 25, 1930. Serial No. 470,742.

The present invention relates to spinning machines or frames, and more particularly to the weight transmitting saddles for the top rolls of the machines. i I

An object of the present invention is to produce yarn of a. more even size than is produced'with present equipment; to reduce to a minimum frictional contact between the saddle and'the rolls ;Lto cause the front leather roll" to run smoother and thus prolong the life of the roll; to reduce power consumption in the'operation of thespinningframe'; and to provide a saddle, thewear on which is confined'to parts which are. readily replaced to 15 save the cost of replacement'of the entire saddle. I

With the foregoing and other objects in view,"the invention will be' morefully de- V scribed hereinafter, and will be more particularly pointed out in the claim appended plying the same to thecontact surfaces between th'eroll shafts 14 and the front and hereto. In the drawings, wherein like symbols refer to like or corresponding parts throughou v the several views, I Figure 1 is a longitudinal section taken through a roller set of a spinning machine or frame, and with a saddle constructed according to the present invention applied I thereto. v p Figure 2is a fragmentary top plan view of the same.

Figure 3 is a detail perspective inverted View of the front saddle, and i Figure 4: is a detail perspective view of the rear saddle.

Referring now to the drawings, Figures 1 and 2 show a roller set as used in a spinning machine or frame, and the setcomprises a series of metal rollers 10, which are the bottom rollers, and against the upper sides of which bear the upper leather covered rollers 11. As shown in Figure 1, the pairs of rollers 10 and 11 are three in number, providing front and rear end pairs and an'intermediate pair. The yarn is pulled through the pairs of rollers and in order to exert the desired pressure on the yarn, pressure is applied to the top rollers 11 so as to urge the same downwardly toward the bottom rollers .50.: 10 by a weight or the like.

According to the-present invention, a saddle is employed. The saddle comprises a front saddle section and a rear saddle sec-1 tion. The rear saddle section is in the form of an elongated relatively flat bar 12 having at its rear end, and at its underside, a concavity or recess 13 adaptedto embrace the shaft orhub portion 14 of the rear top roll 11, as shown in Figure '1, to. hold the rear saddle 12 against longitudinal shifting. The front end of the rear saddlerests upon the upper side of the hub orshaft 14 of the intermediate top roll 11. The rear saddle 12 is provided withoil openings 15 extending downwardly therethrough, and openingagainst the hubs'ori shaft'sections 14 of the top rolls, against which the rearsa'ddle rests. The openings 15 extend upwardly through the bottom of wells 16 adapted to receive grease, or other suitablelubricant, for. sup,-

rear end portionsiof the rear'saddle 12. r I

The rear saddle 12 .is'also provided, inter-, mediate its ends, with an upwardly extendi-ng and rearwardly enlargedlug 17 for cooperation with the front saddle 18, as herein, after explained, tomaintain the front and rear saddle sections inalignment with one another. i 1

The front saddle section 18 comprises an elongated bar which may be offset downs wardly at its rear end, and provided thereat and at its underside with a pair of spaced apart flanges 19prov'i'ding aguide adapted to embrace the-lug 17 for holding the lug slidably between the guides. At the offset, the bar 18 is provided with-an oilreceiving open ing' 20 which extends downwardly :andlea'ds not only to the lugl7, but also to the front Inbricant well16 for supplying oil or grease thereto. 7

Theforwardend of the front saddle or bar 18 is forked to provide forkarms 21,between which are disposed spaced rollers'22 mounted on pins 23, which extend through the rollers and into the fork arms 21. The rollers 22 are so locatedas to project below the .roller edges of the form arms 21, andthe latter are suitably recessedto cooperate with the lower adjacent sides of the rollers 22 in forming a cavity or rest between the rollers, so that the rollers may properly seat the spaced points upon the upper side of the shaft 1 1 of the upper front roll 11. The rollers 22 are adapted, therefore, to not only maintain the front saddle section 18 against longitudinal displacement, but to also reduce frictional contact between the front saddle and the front high speed roller 11, and insure the smooth and even running of the roller without reducing the necessary pressure on the saddle to produce uniform yarn.

The front saddle 18 is provided with a transverse slot 24 for the reception of a stirrup, or the like, by means of which the weight is connected to the saddle, and is also provided with a projection or shoulder 25 in suitable spaced relation rearwardly of the slot 24 for holding the stirrup from slipping,

It is thus apparent that with a saddle of this construction the rear and intermediate contacts between the shafts 1 1 and the ends of the rear saddle 12 are properly lubricated, so as to offer the least possible resistance incident to direct contact, while the front saddle 18 is seated by meansof its rollers 22 on the shaft 14 of the front roller 11 to reduce Wear between the front saddle 1.8 and the front roller'as the latter is driven at a relatively high rate of speed as compared. with the other rolls and, consequently, the desired pressure may be exerted through the rollers 22 to the roll 11 without proportionately increasing the frictional contact or resistance between the same.

When the rollers 22 are worn appreciably by continued and prolonged use, it is evident that these rollers 22' may be quickly and easily replaced by new rollers merely by removing the pins 23, and again replacing them on new pins after such pins are worn. The entire saddle structure, therefore, need not be discarded upon the wear of the bearing surface of the front end of the front saddle, such as has been the custom in the past. The saddles thus last indefinitely, and it is economical and easy to effect a replacement of the bearing rollers 22.

It is also apparent that the overlapping inner ends of the front and rear saddle sections are permitted easy and ready relatively sliding movements one upon the other, incident not only to the arrangement of the lubricating opening 20, but also incident to the positions and the opposite flaring of the lug 17 and theflange's 19.

The weight may be imposed on the saddle by the stirrup or any other suitable device adapted to engage across the upper surface of the front saddle 18 adjacent to the shoulder or projection 25, so that the pressure of the weight is transmitted directly upon the front roller 11, and is also transmitted and dlvided between the intermediate and rear top rollers 11 through the rear saddle section 12.

It will be obvious that various changes in the construction, combination and arrangement of parts could be made, which could be used without departing from the spirit of our invention, and we do not mean to limit the invention to such details, except as particularly pointed out in the claim.

Having thus described our invention, what we claim and desire to secure by Letters Patent of the United States is A spinning frame saddle, comprising a rear section having lubricant wells in its upper side near its opposite ends and having openings therethrough leading from the bottoms of the wells, said rear section also having in its under side a bearing depression in register with the adjacent lubricant opening to seat upon the rear top roll shaft and hold the front end of the section at its adjacent lubricant opening across the intermediate top roll shaft, said rear section further having a forwardly tapering lug on its upper face adjacent the forward well, a front section having a forked front end and provided at the under side of its rear end with a pair of rearwardly diverging flanges to embrace said forwardly tapering lug, said front section also having a lubricant opening through its rear end portion leading to the forward ends of the flanges to conduct a lubricant to the flanges and the lug and into said front well of the rear section.
